Sikafloor 81 EpoCem 21 KG Kit

Self smoothening epoxy-cement floor topping & moisture barrier



Sikafloor-81 EpoCem is a 3-component epoxy modified cementitious self-smoothening floor topping and moisture barrier.


As a moisture barrier (2 mm thick) for epoxy and polyurethane floors.

As self-levelling topping of 1.5 – 3mm thickness for:

  • Levelling or patching concrete surfaces, both unfinished and after grinding or scabbling.
  • Coloured EpoCem floors on non ventilated damp substrates with low aesthetic considerations (ask for technical assistance)
  • Floor toppings beneath epoxy protective coatings.
  • Self levelling toppings that are to be covered with polymer floor coatings, carpets or wooden parquet.
  • Repair and maintenance of vacuum concrete floors.


  • Can be top coated with resin based floors after 24 hours (+20ºC, 75% r.h.)
  • Prevents osmotic blistering of resin based coatings over damp substrates
  • Excellent bond to green or hardened concrete whether damp or dry
  • Waterproof yet permeable to water vapour, allows the substrate to “breathe”.
  • moisture barrier (7-10 days).
  • Self-smoothening – good flowability.
  • Easy to apply to sound prepared surfaces.
  • Solvent free and virtually odourless.
  • Ideal surface preparation with the minimum of delay for the subsequent application of other appropriate Sika epoxy products.
  • High abrasion resistance.
  • Free of chloride.
  • Similar modulus of elasticity and coefficient of thermal expansion to concrete.
  • Good adhesion after long-term water immersion.
  • Excellent mechanical strength.
  • Excellent resistance to water and oils.
  • Will not corrode reinforcing steel.
